This is the first pinball machine to feature 3-ball multiball, although the term "multiball" was not in use when this game was made. The flyer referred to it as the "sensational new Blast-Off extra balls feature".
The flyer also points out Bally's brand new universal transformer and motor which would work on both domestic and export Bally pinball machines. Previously, separate motors were required for domestic and export games. Bally first used this universal motor on their previous game Bally's 1963 'Hootenanny'.
Pictured in this listing is a Early Production game with cabinet serial number JS1007 and playfield tagged as number 1003. Its striped beige and blue light shields match the color contrast of the shields in the monochrome flyer while subsequent production games have opposite contrast using red and yellow. On the backglass, the yellow area behind the spaceship, which extends to the upper left corner of the glass, is the same yellow color as the area around the score reel windows. This background color was changed to a shade of orange in later games.
